To all whom it may concern.-

Be it known that I, PHILLIP HENRY BIEMAN, a citizen of the UnitedStates, and a resident of Chicago,in the county of Cook and State ofIllinois, have made a certain new and useful Invention in Needles forGrain-Binders; and I declare the following to be a full, clear, andexact description of the same, such as will enable others skilled in theart to which it appertains to make and use the invention, referencebeing had to the accompanying drawings, and to letters of referencemarked thereon, which form a part of this specification.

Figure l is a side view showing the invention. Fig. 2 is a top View.Fig. 3 is a sectional view. Fig. 4 is a perspective View of the knife.Fig. 5 is a sectional view showing the knife-seat.

The invention relates to binding-needles for harvesters; and it consistsin the novel construction and combinations of parts, as hereinafter setforth.

In the accompanying drawings the lettera, designates the body portion ofthe needle, having the point b. to which is secured the detachable knife0. The point I) is of conical form and is provided with a seat-cleft 61,extending through it and having in its deepest portion or bottom oifsetse c at the ends of a taper form seat g. The forward ends h of the cheeksof the point are notched, usually in concave form, as indicated, toengage the shoulders of the point-knife. This steel knife 0 consists ofa conical point portion Z and a thin plane body Z, the Whole being oftriangular form and a little broader than the point 5 of the needle, sothat the cutting edges m of the body will project outward or stand outfrom the conical point of the needle. The heel or base of the knife isformed with a middle notch n, adapted to fit neatly the seat g of thecleft in the needle-point, the wings or extensions 'w at the ends ofthis notch fitting the offsets e of the base of the cleft. Theknife-point Z has shoulders 25, usually of convex form, presentingrearward to engage the concave ends of the cheeks of the needle-point.The knife is secured in position by its engagement with the seat and 01fsets of the cleft and by the pin or screw 8, the ends of which should becountersunk in the walls of the point. The knife can be readily removedfor sharpening or repair.

Having described this invention, what I claim, and desire to secure byLetters Patent, 1s

1. The combination with a cleft pointed harvester-needle, of a removableshouldered point-knife, substantially as specified.

2. The combination with a cleft harvesterneedle,of atriangular-shouldered point-knife, having a notched base, and means forattaching said knife to said needle, substantially as specified.

In testimony whereof I affix my signature in presence of two witnesses.

PHILLIP HENRY BIEMAN.
